Jose Quintana will move from southside to northside Chicago as the White Sox traded him to the Cubs on Thursday.

Quintana, a subject of trade rumors for about a year now, was moved for four prospects: Eloy Jiménez, Dylan Cease, Matt Rose and Bryant Flete.

The deal makes perfect sense for both sides. The White Sox continue to rebuild and stack their farm system while the Cubs get the starting pitcher they so desperately need right now.

It hasn’t been the smoothest season for Quintana, who has posted an ERA near 5 thus far. The lefty has, however, figured things out allowing just 12 runs over his last seven starts.

As for the guys the Cubs gave up, Jimenez and Cease were their No. 1 and 2 prospects…so acquiring Quintana wasn’t easy. But to snag a top arm in baseball, you have to part ways with some of the farm. The Red Sox did the same thing when they gave up Yoan Moncada and Michael Kopech for ace Chris Sale last winter.

The Brewers hold a small lead over the defending champion Cubs in the NL Central. Now that the Cubs have another capable arm in that rotation, look for the division race to get pretty interesting in the second half.

The White Sox, on the other hand, obviously are focused on their future. And that future looks very, very bright.
